BobF: yes I am running 1.4s. Since that is what is advertized, I believed them and I got the boards before this problem was discovered.
irrigating: Am I perfectly qualified? no. I have built ~15 working systems. Does your mother dress you funny? yes.

In general, I would agree with you. If you have a customer with multiple returns of a product, it is logical to think the customer is doing something incorrect. Two items point to other causes:
--both problem types I have encountered has been detailed by many, many, many people at OCWorkbench Forum.
--one board worked perfectly under heavy loads for 8 weeks, a second for 10 weeks, and the two other boards are still working since early Sept.
Don't get me wrong. If someone asked me early Nov. what mobo to buy, the answer would have been K7S5A!!! I was very pleased. However, one FSB 133 -> FSB 100 stability problem and two cold boot problems later, I am not as happy a camper.
I wanted this mobo to succeed, you know, take a little air out of Asus, Abit, etc. (maybe cause everybody to lower their prices

) Also, I realize all mobo's have problems. That being said, the 1.4/k7s5a is a real bad pair.
Like I said before
read some of the posts. MrAthlons testing had 26 of 27 with memory errors!!! Some posts are newbies "I put the ram in backwards, what do I do now?" but many are by technically competent people having similar problems.
jwong: your "50% rma is crap" is hopefully true. My personal RMA rate is 60% with this board. It is worth noting that the only faulty electronic equipment I have ever RMA'd was a Mag monitor ~8 yrs ago and three of five k7s5a's. I am one of the lucky ones. At least I have two boards that work. This will be the last k7s5a RMA for me. It costs $10 each time I ship one back. The next one that goes bad will be subjected to the "resistor fix".
I closing, this mobo can be great. If you get one, I hope it never goes bad. I was just trying to educate the buyers.
